Title: Improvements in or relating to tobacco smoke-filtering elements
Inventor: TOUEY GEORGE PATRICK
IPC: A24D3/16
Filed: 1958-07-03
Abstract: Filtering elements for cigarettes, tobacco pipes or cigar or cigarette holders comprise a bundle of continuous synthetic filaments with particles of a water-insoluble calcium or magnesium salt distributed over their surfaces and bonded thereto by an agent miscible with, or a solvent for, the filament material.  The filaments may be bonded together at random points. A salt of meta-, ortho- or pyro-phosphoric acid or of stearic or carbonic acid may be used, and the particles may be between 0.1 and 10 microns in size and form from 5% to 60% of the filtering element.  The major portion of the particles may be of a size less than twice the filament diameter but greater than one-tenth the filament diameter, and preferably, at least 80% of the particles are of less than filament diameter.  The particles may be blown on to the filaments, or applied thereto as a slurry in cold water or in a volatile organic vehicle, or they may be applied electrostatically to filaments in the form of a banded tow. Alternatively, the particles may be dusted on to a banded tow of filaments, the surface of which is wetted with adhesive, e.g. dextrin glue, or with plasticizer, before, during or after dusting, e.g. a slurry of plasticizer, salt particles and perhaps water or alcohol may be used.  The filaments may be nylon, polyamide, polyester or regenerated cellulose, or of cellulose acetate having 4 to 10 crimps per inch, 3 to 16 denier and 4,000 to 35,000 filaments to a bundle. The plasticizer may be glycerol triacetate or tripropionate, triethyl citrate, or di-(methoxyethyl)phthalate with or without sodium lauryl sulphate.  After treatment with plasticizer and particles, a banded tow may be returned to its original shape and bonded by heat treatment after forming into paper-wrapped cigarette filter rod lengths.  To aid particle bonding, the filament surfaces may be treated with an oil, before or after adding the plasticizer and particles.  The oil may comprise from 3% to 8% of the filtering element and is colourless, odourless, tasteless, non-volatile and non-toxic, and insoluble in the plasticizer at room temperatures although it may be soluble therein at elevated temperatures so that it may be applied dissolved in the plasticizer applied hot.  Suitable oils are castor, cottonseed, almond, coconut, peanut and olive; pharmaceutical grades of light, medium and high viscosity mineral oils, lauryl alcohol and glycerol oleates, laurates and ricinoleates. Quantitative process examples are given.

Filed: 1962-06-04
Abstract: 979, 817. Digital computers. RADIO CORPORATION OF AMERICA. June 4,1962 [June 12, 1961], No. 21564/62. Heading G4A. In a computer control system in which the contents of a register control the operation of various units in the computer, the communication arrangement between the register and the units comprises a recoder responsive to the contents of the register and producing outputs on a plurality of individual conductors arranged in groups to form "buses". Cross-talk in the communication arrangement is thus minimised. The arrangement described is for a computer in which an instruction includes an "operation word" comprising two parts, the parts each consisting of 9 bits and identifying registers from which and to which a data word is to be transferred. In the general arrangement shown in Fig. 2, an instruction word from the computer memory (not shown), is entered in a register 10a, the outputs from the operation word stages are decoded at 12a and applied to a sequencing machine instruction generator 22, each coded output of which is applied to a bit pattern generator 24 which produces a characteristic pattern for each machine instruction signal, this pattern being registered at 26. The register 26 is connected to recognition gates 20a which respondto the pattern stored in the register 26 to produce computer unit control signals. The circuit operates under the control of clock pulses CP1-CP4. As shown in Fig. 5, the register 26, which comprises nine flipflops 26a for controlling the read out of data from 512 different registers (not shown), and nine flipflops 26b for controlling the read-in to these 512 registers, is connected via 18-wire buses 36, 38 connected to both output terminals of all the flipflops to encoders 40, 42 comprising arrangements of "none" gates (Fig. 6, not shown). The output leads from the encoders 40, 42 each consist of three 8-wire buses and the arrangement is such that in each 8-wire bus only one wire carries a "I", all the other wires carrying a "0", thereby reducing cross-talk. The 8-wire buses are connected to 1024 recognition gates 20a, these gates being distributed among the registers to be controlled. The encoders 40, 42 are located near to the register 26 and the recognition gates 20a are located near to their respective controlled registers. The data transmission between the 28-bit registers controlled may be synchronous or asynchronous. In a modification (Fig. 9, not shown), a combination of a 1 in 16 encoder and a 1 in 8 encoder is employed.
